Sintering machine and the like

Fig. 1 is a side elevation of the drive end of a Dwight-Lloyd sintering machine, omitting parts which are unrelated to this invention;

Fig. 2 is a transverse section on the line A-A of Fig. 1;

Fig. 3 is an elevation, partly in section, of parts of the lubricating device.

The pallet frames 1 receive in succession a charge of the material to be sintered from the hopper. 2 as they travel past the lower end thereof, moving from right to left. They are driven by a sprocket wheel 3. The charge is ignited at the top as the pallets come under an igniting burner 4. A down draft is main tained as the pallets pass over a wind box 5 WlllCl'l sucks the air through the charge and through the grate forming the bottom of the pallet.

At the right-hand end of the supporting frame-work there is a guide casting 6 with a curved lip to ease the passage of the pallets from the driving wheel 3 to their fixed supports. From the guide castings 6, the pallets pass on to dead plates 7 and thence on to wearing strips 8. They should rest with a close fit on the dead plates and wearing strips so as to prevent a leakage of air at these points, which leakage cuts down the efficiency of the fans drawing air out of t is wind box 5.

The lubrication of such machines heretofore has been by means of compression grease cups or similar devices placed at intervals along the castings 9 which form the side copings of the wind box. These are not easily accessible, and generally neglect, dust and heat have combined to make them inoperative or only partially operative. This has resulted in great wear on the pallet frame and the wearing strips, requiring frequent renewal of these parts and causing delay and expense. I propose to lubricate them by devices which are removed from the hottest part of the machine and which supply the lubricant continuotjsl'yand under easy observatibii and cont IOQ. I

Froin the oiitleteiid ofthe injector, pipe 17 projectsforwartl'ly to s ans. beyond theend offlisgifide cestia I andis bent to direct the oil on to the curved end ofthe castinganol under the surfaces of the pallets. The oiling arrangement is duplicated for the two sides of the machine.

In operation, the sight feed valve is regulated for the desired quantity of oil. The air valve 16 is then regulated so that the air will carry the lubricant through the pipe 17 spraying it between the upper and lower surfaces of the guide and pallets, respectively. The operator stands on the operating floor 18 where the oiling operation is directly under his eye and where he can change the oil feed at will. He needs only to maintain the oil tank full. The oiling is a continuous operation. It not only serves the usual oiling functions but also maintains a very efiective film between the moving and the stationary parts, making an approximately gas tight contact andthus increasing the efficiency of the suction fan.

Various modifications may be made by those skilled in the art without departing from the invention as defined in the following claims.

What I claim is 1. The combination with a machine having a series of pallets and means for advancing them onto and sliding them over a fixed support of means for projecting a lubricant between the surfaces of said parts where the pallets are guided on to the fixed support.

2. The combination with a machine having a series of pallets sliding over a fixed support of means for projecting a lubricant between the surfaces of said parts where the pallets are guided on to the fixed supports, said projecting means comprising a pipe carrying a continuous supply of air under pressure in order to continuously lubricate such surfaces.

3. The combination with a machine having a series of allets sliding over a fixed support of means or projecting a lubricant between the surfaces of said parts Where the pallets are guided on to the fixed supports, said projecting means including a regulable feed for the lubricant and means for continuously pro ljecting it at the point stated.

4. he combination with a sintering machine having a series of pallets and means for advancing them over a fixed frame and between an igniter and a wind box of means for supplying a lubricant to the under surfaces of the pallets at a point Well in advance of the igniter. 5. The combination with a sinteringmachine having a series of pallets travelling over a fixed frame and between an igniter and a wind box of means for supplying a lubricant to the under surfaces of the pallets at a point well in advance of the igniter, said Inricating means including a regulable feed and means for continuously projecting the lubricant at the point stated.

In Witness whereof, I have hereunto signed my name.

EDWARD CUDDIHY.
